Enable EEPROM to force direct sampling mode 
Re-purpose remote-enabled EEPROM flag to determine if direct sampling mode should be forced ON. Useful for apps that don't have any direct sampling mode settings in their GUI.

offset tuning -> bias tee hack 
Use the offset tuning button to enable the bias tee on the V3. Offset tuning is not used for the R820T so this is okay and allows us to toggle the bias tee on software that hasn't implemented specific bias tee controls.

Steve Markgraf 81833a1cf6 lib: disable usbfs zero-copy support by default 
Although we added a detection mechanism for the presence of the Kernel
bug earlier, reading from the incorrectly mapped memory might cause a
bus error on some ARM systems.

With the overall performance benefit being rather minimal for the
data rates of rtl-sdr, disable zero-copy by default.

Stephen Blinick da0c8ea073 Clean out stale data in ring buffer when client disconnects. 2019-02-10 15:23:42 -07:00
Stephen Blinick d0e7dcde04 Perf: Replace rtl_tcp linked list with ring buffer 
Removed the linked list structure, locking, and malloc/free on each USB callback.
Replaced it with a non blocking ring buffer for performance.  This resulted
in a large performance improvement when using an Raspberry Pi or Raspberry Pi Zero W
as a rtl_tcp server.  The sample rate could be doubled and instead of wired ethernet
wifi could be used.  Frequnecy change lag was reduced greatly also.
